Midi files all ok but now no sound at all from them otherwise all else is ok. I loaded 3a recently and I also began using pedals.

Maybe you sent volume controll#7 via pedals. Also check control#11 expression. Go into your parameter windows for volume/exspression, see if it is showing "O" levels.

Re Midi not sounding thanks for Reply from Fran Carango perhaps its my Age !!! but I cannot get to it. I notice Vol balance is correct.ie song v Right no mutes on that I can see. I pressed Song Play and entered song number pressed Gm and it shows 63. ??
Any more info please?
